For the realization method of microwave frequency multiplier, the principle and design of step recovery diode frequency multiplier and bipolar transistor frequency multiplier were discussed. Tri-port non-line resistant frequency multipliers have high efficiency and stability, and they are widely used in modem communication systems. A better microwave frequency 16 multiplier of L-band was developed by twice 4 multiple. Its circuit was optimized and simulated by ADS and the impedance is matched by capacitance and inductance. The output power of 16 multiplier is 10.67 dBm, spurious is > 75 dB, harmonics is > 60 dB, electric current is 110 mA. It can realize multiplying and satisfy the system of microwave frequency source, because of its pure spectrum and high temperature stability.
